Running Files with .mp4 on Windows Media Player RRS feed

  • Question

  • Is there a codec for running .mp4 on Window Media Players. If so where can I get it. I have a file that when I try to open it in Windows Media Player it tells me that "The selected file has an extension (.mp4) that is not recognized by Windows Media Player, but the Player may still play it. Because the extension is unknown by the Player, you should be sure that the file comes from a trustworthy source."

    system: Windows Vista Ultimate (service pack 2), 64 bit OS
